Then, pulling the sliding column downwards moves the sliding plate along the chute. The sliding plate gradually descends, causing the roller to contact the inner wall of the tunnel. At this point, pulling the main body moves the roller, causing it to rotate. The roller drives the first transmission roller to rotate, which, in conjunction with the transmission belt, drives the second transmission roller to rotate. The second transmission roller, through the transmission column, drives the bevel gear to rotate. The bevel gear and the bevel teeth mesh together, causing the mounting column to rotate. The mounting column then drives the limit wheel to rotate, which in turn drives the cable to be transported, thus keeping the cable neatly transported inside the tunnel and preventing the cable from bending inside the tunnel, which would increase the cable length. 2. When the cable is being transported, the pulling of the cable gradually drives the take-up roller to rotate. The take-up roller drives the first limit plate to rotate, the first limit plate drives the first transmission gear to rotate, the first transmission gear drives the rotating shaft to rotate, a set of rotating shafts drives the second bevel gear to rotate, the second bevel gear drives the threaded column to rotate through the first bevel gear, the threaded column cooperates with the rectangular column to realize the screw movement, which in turn drives the rectangular column to drive the extrusion column to extrude the take-up roller, making it easy for the cable on the outside of the take-up roller to loosen during laying.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 8 In this embodiment of the invention, a cable laying device for power engineering construction includes a main body 1. The main body 1 has a guide plate 6 inside, and a through groove 29 is opened inside the guide plate 6. A slide plate 30 is slidably connected inside the groove 29. A cavity is opened inside the slide plate 30. A cable outlet pipe 24 is provided at the bottom of the cavity. Rollers 25 are rotatably connected to both ends of the slide plate 30. A first transmission roller 34 is connected to one end of the roller 25. Mounting columns 33 are rotatably connected to both sides of the cavity through mounting brackets. Limiting wheels 32 are fixed at both ends of the mounting columns 33. Conical teeth 36 are opened inside the mounting columns 33. Conducting columns 38 are rotatably connected to both sides of the cavity. A second bevel gear 37 that meshes with the conical teeth 36 is fixed at one end of the conducting column 38. A second transmission roller 39 that cooperates with the first transmission roller 34 is fixed at the end of the conducting column 38. A transmission belt 35 is wound around the outside of the first transmission roller 34 and the second transmission roller 39.

[0018] In this embodiment: the guide plate 6, together with the slide plate 30, is used for the conduction of cables with protective shells. The slide plate 30 and the guide plate 6 are slidably connected. The bottom of the slide plate 30 extends through to the inner wall of the tunnel bottom, so that the roller 25 contacts the ground at the bottom of the tunnel. Then, the main body 1 is manually pulled, which drives the roller 25 to move. The roller 25 rotates while moving, and the roller 25 drives the first transmission roller 34 to rotate. Through the transmission belt 35, the second transmission roller 39 is driven to rotate. The second transmission roller 39 drives the bevel gear 37 to rotate through the transmission column 38. The bevel gear 37 and the bevel teeth 36 cooperate with each other to drive the limit wheel 32 to rotate. The two sets of limit wheels 32 clamp the cable and drive the cable to gradually flow out from the outlet pipe 24, so that the cable is laid more neatly inside the tunnel, avoiding bending and reducing the length of the cable.

[0019] Please refer to this carefully. Figure 1 The inner walls on both sides of the main body 1 are provided with sliding grooves 10. A sliding block 13 is slidably connected to one end of the sliding groove 10, and a fixing block 14 is fixed to the other end of the sliding groove 10. A scissor lift 12 is rotatably connected to one side of the fixing block 14 and the sliding block 13. An electric push rod 11 is installed inside the mounting grooves 15 on both sides of the main body 1. The output end of the electric push rod 11 is connected to the sliding block 13.

[0020] In this embodiment: the electric push rod 11 is activated to drive the sliding block 13 to move. The movement of the sliding block 13, in conjunction with the scissor lift 12, reduces the overall width of the main body 1, which can adapt to tunnels of different widths.

[0021] Please refer to this carefully. Figure 1 and Figure 2 The main body 1 has a take-up roller 2 inside. The take-up roller 2 has a first limiting plate 3 fixed on both sides and a second limiting plate 5 fixed on one side of the first limiting plate 3. The take-up roller 2 has a limiting groove 18 inside. A second transmission gear 19 is rotatably connected at the middle position inside the limiting groove 18. Rotating blocks 4 are rotatably connected on both sides of the main body 1. A first rack plate 20 that penetrates into the limiting groove 18 is fixed on one side of one set of rotating blocks 4. A second rack plate 21 that penetrates into the limiting groove 18 is fixed on one side of another set of rotating blocks 4. The first rack plate 20 and the second rack plate 21 mesh with the second transmission gear 19. The first rack plate 20 and the second rack plate 21 are symmetrical at their dots.

[0022] In this embodiment: when the width of the main body 1 changes, the first rack plate 20 and the second rack plate 21 move symmetrically under the action of the second transmission gear 19, so that the take-up roller 2 is kept in the middle position of the main body 1, which can ensure the normal output of the cable.

[0023] Please refer to this carefully. Figure 1 and Figure 8 The guide plate 6 is rotatably connected to two sides of a rotating shaft 8. A first transmission gear 9 is fixed on one side of the two sets of rotating shafts 8. Teeth that mesh with the first transmission gear 9 are fixed on the outer side of the first limiting plate 3. A second bevel gear 44 that penetrates into the guide plate 6 is fixed on the other side of the set of rotating shafts 8. A rectangular groove 40 is opened on the top of the guide plate 6. A rectangular column 41 is slidably connected inside the rectangular groove 40. A threaded column 42 is threadedly connected to the bottom of the rectangular column 41. A first bevel gear 43 that meshes with the second bevel gear 44 is fixed at the bottom of the threaded column 42. The pitch of the thread on the outer side of the threaded column 42 gradually decreases from bottom to top. An extrusion column 7 is installed on the top of the rectangular column 41.

[0024] In this embodiment: the first limiting disk 3 and the first transmission gear 9 cooperate with each other. When the take-up roller 2 rotates, the first transmission gear 9 rotates. The first transmission gear 9 drives the second bevel gear 44 to rotate through the rotating shaft 8. The second bevel gear 44 drives the first bevel gear 43 to rotate. The first bevel gear 43 drives the threaded column 42 to rotate. Under the action of gradually increasing pitch, the upward speed of the rectangular column gradually increases, which is used to cooperate with the cable with gradually increasing number of turns. This allows the extrusion column 7 to better fit the cable wrapped around the outside of the take-up roller 2 and prevent it from loosening.

[0025] Please refer to this carefully. Figure 4 and Figure 6 A rotating ring is installed on the outside of the rotating shaft 8. One side of the rotating ring is connected to the guide plate 6 through a fixing frame. Two sets of winding columns 23 are fixed inside the cavity. Dustproof shells that cooperate with the first transmission roller 34 are provided on both sides of the slide plate 30. Connecting columns 16 are fixed on the inner walls of both sides of the main body 1. A sliding column 17 is slidably connected to one side of the connecting column 16. The sliding column 17 is connected to the guide plate 6.

[0026] In this embodiment: the rotating ring, in conjunction with the fixed frame, provides good support, making the rotation of the shaft 8 more stable. The two sets of winding columns 23 allow the cable to pass over the top of one set of winding columns 23 and out through the top of the other set of winding columns 23 before entering the outlet tube 24, which can provide good support for the cable and prevent the cable from shaking. The connecting column 16, in conjunction with the sliding column 17, ensures that the guide plate 6 is always in the middle position of the main body 1 when the width of the main body 1 changes. At the same time, the second limiting plate 5 is in contact with one side of the first transmission gear 9, thereby preventing the guide plate 6 from shifting horizontally.

[0027] Please refer to this carefully. Figure 5 and Figure 6The top of the slide plate 30 is slidably connected to a slide column 27. A locking plate 31 is fixed to the top of the outer side of the slide column 27. The top of the guide plate 6 and the two sides of the slide groove 29 are provided with locking grooves 22 that cooperate with the locking plate 31. The bottom of the slide column 27 is fixed with a first limiting plate 26. A return spring 28 is installed on the top of the first limiting plate 26 and the outer side of the slide column 27.

[0028] In this embodiment: the sliding column 27 is manually pulled, which drives the locking plate 31 to move upward. The locking plate 31 disengages from the locking groove 22, thereby facilitating the movement of the slide plate 30 inside the sliding groove 29. After the position of the slide plate 30 is adjusted, the sliding column 27 is released. Under the action of the return spring 28, the sliding column 27 drives the locking plate 31 to quickly return to its original position, allowing the locking plate 31 to enter the interior of the locking groove 22, thereby completing the installation and fixation of the slide plate 30, thus adapting to tunnels of different depths.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
